Productive sessions. Nutplates for cowling hinges by Richard, Successfully re-routed rudder cables through grommets in tail by Garrett. Sanded fairing and removed canopy for further trimming. Richard learned to secure castle nuts with cotter pins. Maggie "the pretzel" Colwell tracked down some squeaking noises when moving the sticks. Turns out the pushrods rub on the bottom of the lightening holes. Larry discussed the issue with Van's and it appears the torque arms are not positioned properly. The cause in unclear. Will need to be sure the flap actuator is not extended at all, and verify the geometry of the torque tubes. New torque tubes, aileron push rods and spacers have been ordered.
